    On a particular day in the year 2007, the prices (x) of six shares were as follows:
    807, 967, 727, 167, 207, 767
    Use the coding y=x-7 all divided by 80 to work out the mean value of the shares.
    The answer is 607 but why would they give you coding when you can directly get it from the data.

    But they do not ask you to use the coding to convert the 7.5 back to original mean
